Switch to a WW12SL wad and your problem will be gone with the New AA hull.
Problem solved.......

The Remington and CF Winchester’ are not straight wall hulls , they are tapered. I suggest what mg1polo says and use the 12SL wad. Also take a look at your first stage crimp starter If the crimp starter is too shallow it will not fold all the way over on the final crimp.

All of the hulls that you are attempting to reload are, Tapered Wall.

I cannot figure out why some (newer hulls) seem to load fine and the crimp closes without issue and many others have a comprised sidewall and open crimp. Can’t figure out why some are fine and many are not.

The newer AA HS hulls have less internal capacity(due to base wad) then the Remington or AA CF. So most of your issue is stack height. As MG said you should change wad for that hull and adjust the crimp station. Also AA HS seem to have more variances in length from one hull to the next but you should be able to adjust the loader to get a happy medium so you get a few with a slight swirl and some with a small hole.

I suspect the wad is getting caught on the base wad. If you pull the wad out, is the powder cup damaged?

Been there; done that. AA HS hulls need either a hull (edit: WAD!) that is designed for them ( a bit shorter) or a denser powder ( like tightwad). It is a stack height issue. Yes, curses and damnation for the published loading data that still, decades later, refuse to acknowledge that the AA HS hulls require their own specific load data.

If you switch wads to a 12SL instead of the 12L that you are using, your problem will be gone, period!

Your assumption that all these hulls are interchangeable and load with the same machine settings is unwarranted as clearly demonstrated by your difficulties with the WW AAHS hull.

 

[Curly N]

When the stack height inside the hull is too tall, the WWAAHS hull will collapse and pucker because you are squashing it.

Ditto what polo says, Been loading AA,s from CF thru 4 Gens of HS hulls, what he said is exactly true. Best part is the hulls are free all over the place. Beats me why people are scrambling for Gun Clubs, adjust your pre-crimp and all the brass hulled hulls are yours for the taking!

Any 1 oz. AA-style wad will solve your problem with the AA new-style hull and a bulky powder like your American Select. The Green Duster ought to be a good choice. Like most have said, your stack height is too tall and using a wad with a bit shorter crush section will bring the stack height down and cure the problem.

That business about a "cocked wad" is hogwash. The sidewalls on the new style AA are weaker than the old style AA and that what causes them to buckle when the stack height is too tall.

For MEC’s sake.

Should not the title of this thread be edited?? It is not a MEC issue but component issue.

Not Always 😎

I am assuming you are referring to the issue that very few people had with some of the original CB wads catching on that cup's lip on the way down with wads that seated down into that insert. They do offer wads all labeled with a "lead in taper" on the wad. It's a solution to a problem that really doesn't exist.

 

[tommy gray]

i have loaded that same load and use 12sl wad and no problmes at all

It is operator error not using correct powder wad combination to achieve stack height loading 101 not rocket science

A very helpful and mostly accurate statement I do appreciate your input .

From Claybuster's site.

Lead-In Taper​ Some Claybuster Wads now feature a lead-in taper on the powder cup that reduces the possibility of catching on the insert in the HS Hull.

I’ve had wads catch on that insert. When I said as much on here some lumber duck told me I was lying. But....

So I just disregarded anything further from them.

Dirt they are truly a great fix for an HS hull and easy to work with I have used them exclusively when they first became available.
Thanks for you reply 👍
